You can check the inclusion criteria for these trials online. This lets you check all of the specific criteria that you must meet in order to qualify for potential entry into any given trial. You will also find a list of all of the factors that would specifically exclude you from participating. These are listed on the database. It may save you some time and effort later.

Make sure that if you are considering involvement in a clinical trial, it is officially listed and regulated.

By all means take up the offer of a free initial consultation and find out about this clinic but remember there is no such thing as a free lunch!!! If it looks and sounds too good to be true then it will be too good to be true. Don't be pushed into anything. Too often places will promise miracles to get you hooked in but then the reality is something else entirely.
